Impressive, although not nearly as impressive as the set-up or 40 mile ride done by former RSU colleage “Unibiker”. Most posters on this thread probably joined the forum after Unibiker had departed. Had to look around a bit as his old gallery, but here’s the link to some pictures. Rather than have a friend handy to catch the front wheel coming off, he just pulled it permanently, then chopped the fork off as well and re-aligned the seat to be optimized for the “wheelie” position. In a very early version he had a small 16" wheel up front for emergencies, but then got good enough to just commit to no second wheel.
Here is one of several threads started by Unibiker to chronicle the increasing distances he was achieving on his pioneering creation.
